Information current as of 2020
In Alaska, a person (developer) may need an Alaska Oversize and/or Overweight Permit (Permit) from the Commercial Vehicle Customer Service Center (CVCSC) of the Alaska Department of Transportation and Public Facilities (DOT&PF) division of Measurement Standards and Commercial Vehicle Enforcement (MSCVE) to operate or move a vehicle or load on any state highways if that vehicle or load is of a size or weight exceeding the limits described in Alaska Admin. Code. tit. 17 § 25.011. Alaska Admin. Code. tit. 17 § 25.011; Permit Manual, § 2 (General Information). The DOT&PF has authority to issue permits for vehicles or loads exceeding legal limits. Alaska Stat. § 19.05.010-040; Alaska Admin. Code. tit. 17 § 25.011; Permit Manual, § 2 (General Information). The legal size and weight limits for vehicles and loads are defined in Alaska Admin.

Oversize/Overweight Permit Process

6-AK-a.1 to 6-AK-a.2 - Does the Load Exceed Size or Weight Limits for State Highway Transportation?

If the vehicle or load exceeds the size and weight limits set forth in Alaska Admin. Code. tit. 17 § 25, the developer must obtain a Permit from the MSCVE to travel on the state highway system. Alaska Admin. Code. tit. 17§ 25.011. A developer must obtain a Permit for loads or vehicles that exceed the following limitations:


  • The width of a vehicle, including load, may not exceed 102 inches, and equipment attached to the transport vehicle may not extend more than three inches beyond the 102-inch width limitation on each side;
  • A vehicle, including its load, may not exceed a height of 15 feet or 17 feet if operating between the Fox Weigh Station and Prudhoe Bay on the Dalton and Elliott Highways;
  • Semitrailers and trailers must not exceed 53 feet in length;
  • The length of a power vehicle may not exceed 45 feet;
  • The overall length of a combination of vehicles, consisting of a truck and one cargo-carrying vehicle or a truck tractor and two cargo-carrying vehicles, may not exceed 75 feet, however a combination of a truck tractor and one cargo-carrying vehicle is not subject to an overall length limit;
  • A load or equipment may not overhang or extend more than 3 feet beyond the front bumper of the vehicle or 4 feet beyond the rear of the vehicle; and
  • Long combination vehicles (LCVs) traveling on National Highway System routes may not exceed the maximum lengths outlined in Alaska Admin. Code. tit. 17 § 25.014.

Alaska Admin. Code. tit. 17 § 25.012.


Vehicles and loads exceeding the weight limitations outlined in Alaska Admin. Code. tit. 17 § 25.013 will require a permit. If more than one weight limit applies, the most restrictive limitation of tire loading, axle weight, or gross weight will be used to determine the maximum allowable weight.

Note: The information presented above is a general overview of size and weight limitations for the state highway system. For complete guidance, including information on requirements for specialized equipment and vehicles utilizing supplemental axles, see Alaska Admin. Code. tit. 17 § 25.012-17.

6-AK-a.3 - Application for Oversize, Overweight, or Oversize & Overweight Permit

For vehicles or loads that exceed legal limits, the developer must apply for one of three types of available permits:

  • Oversize Permit: Issued for any vehicles or vehicle with a trailer and a load that exceeds legal dimension for size only.
  • Overweight Permit: Issued for any vehicle or vehicle with a trailer and a load that does not exceed legal dimensions for size but does exceed legal weights.
  • Oversize & Overweight Permit: Issued for any vehicle or vehicle with a trailer and a load that exceeds both legal dimensions for size and legal weights.

Permit Manual, § 3.1.

Permit forms are available at the CVCSC website (see ADOT&PF reference page for link). Permit Manual, §§ 4.1-2 lists the information required for the application. The application must include:

  • USDOT number, if applicable.
  • The name of the carrier or individual performing the move;
  • The name of the company or individual paying for the permit;
  • The developer’s contact and billing information;
  • The requested move date;
  • The origin and destination of the move;
  • The planned route for the move;
  • The license numbers or equipment serial number of the vehicle or trailer used for the move;
  • A complete description of the equipment or load;
  • Details on the dimensions of the equipment or load;

Note: Overweight vehicles or loads require additional information on the application. For details on these additional requirements, as well as a more detailed description of the required information listed above, see Permit Manual, §§ 4.1-2.

6-AK-a.4 – Is the Application Complete?

If the MSCVE determines that the application is incomplete, or requires additional information, the MSCVE will contact the developer and request the information or materials necessary to complete the Application.

6-AK-a.5 - Review Application Materials

MSCVE will review and process the developer’s application and make a determination on whether or not to issue a permit. Permit Manual, § 2 (General Information), § 2.4.

6-AK-a.6 - Does the MSCVE Approve the Developer’s Application?

The MSCVE will issue a permit to the developer if it determines the following:

  • The overweight vehicle or load is non-divisible;
  • The state's best interests are served by the permit;
  • The usefulness of the traveled highways is not diminished;
  • The safety of other users is not compromised; and
  • The traveling public will not be unreasonably inconvenienced.

Alaska Admin. Code. tit. 17 § 25.320(a).

MSCVE may deny a permit to a developer who has incurred certain violations described in Alaska Admin. Code. tit. 17 § 25.320(f) within 90 days prior to requesting the permit. In addition, the MSCVE will not grant an Extended Period Permit for vehicles or loads matching the specifications outlined in Alaska Admin. Code. tit. 17 § 25.320(c).

6-AK-a.7 – Pay Required Fees

Upon approval of a permit application and the issuance of an oversized and/or overweight permit, the developer must pay any fees required for the use of the permit. The amount of the fee is determined based on the size and/or weight of the vehicle or load and either the number of trips approved in the application or the length of time for which the permit is approved. Alaska Admin. Code. tit. 17 § 25.380. For a complete explanation of how permit fees are calculated, see Alaska Admin. Code. tit. 17 § 25.380.

6-AK-a.8 - Oversize and/or Overweight Vehicle Permit

The MSCVE may establish time limitations for movement, designate routes, limit the number of trips, or otherwise restrict the movement of oversize or overweight vehicles and loads when issuing a permit. Alaska Admin. Code. tit. 17 § 25.320(a)-(b). The MSCVE may issue permits for the following lengths of time:

  • Single Trip: Permits may be issued for a single move from a starting point to a destination for a three (3) day time period.
  • Extended Period Permits: A permit which falls within certain parameters for size and weight may be issued for longer periods of time than a single trip permit. These permits are usually issued in 30, 90, 180, 270, and 365-day increments of time. An annual or 12-month time period is the longest period of time for which a permit will be issued. These permits can only be renewed by request from the developer.
  • Multiple Move Permits: A permit may be issued for multiple moves that consist of the same load and the same vehicle or vehicle with trailer traveling from the same origin to the same destination. The number of moves must be exact as there will not be a refund for any unused portion of the permit.

Permit Manual, § 3.2

If MSCVE approves the application, the developer must ensure that all activity is compliant with the conditions of the permit and the requirements outlined in Permit Manual, §§ 2.5-6, 5-10, 12-16. The developer may still be subject to “stop orders” by law enforcement officers or orders to offload a part of the cargo if the vehicle or load violates regulation or the terms of the permit, or if an officer believes an order is necessary to protect public safety or the safety of the highway. Alaska Admin. Code. tit. 17 § 25.350-360. MSCVE may also revoke permits for violations of regulations or permit terms, or for unauthorized alteration of permits. Alaska Admin. Code. tit. 17 § 25.370.

6-AK-a.9 – Appeal Decision (If Applicable)

If the MSCVE denies the developer’s permit application, the developer may pursue the appeal process outlined in Alaska Admin. Code. tit. 17 § 25.375. The developer must submit a written appeal to the Director of MSCVE no later than seven (7) days after the date of the denial, and the appeal must include the following elements:

  • The grounds for the appeal; and
  • Any argument in support of the appeal.

Alaska Admin. Code. tit. 17 § 25.375(a)

The MSCVE Director may address the appeal in one of two ways:

  • By holding a hearing within 10 days of receiving the appeal according to the guidelines outlined in Alaska Admin. Code. tit. 17 § 25.375(b), and by issuing a written decision within 10 days after the hearing; or
  • By issuing a written decision without a hearing within 10 days of receiving the appeal if he/she does not consider a hearing necessary.

Alaska Admin. Code. tit. 17 § 25.375(b)-(c).

If the MSCVE Director affirms a denial, the developer may pursue redress by appealing to the Alaska Superior Court within 30 days from the date the decision was mailed or distributed, as per Rule 602 of the Alaska Rules of Appellate Procedure. Alaska Admin. Code. tit. 17 §25.375(d). Additional guidance on the appeals process is available within Alaska’s Appellant Instructions for Administrative Appeals to the Superior Court.
